Figure 3From: Tailoring the grooved texture of electrospun polystyrene nanofibers by controlling the solvent system and relative humidityCross section of representative fibers. The fibers were fabricated by electrospinning 20% (w/v) PS solutions with various THF/DMF ratios. (A, B) 4:1, (C, D) 1:1, and (E, F) 0:6 v/v. RH 60%, collecting distance 15 cm, feeding rate 1.5 ml/h, and applied voltage 12 kV.Back to article page
